baking diffuse map

Hi Muqaddas mmuqaddas ,

You need to Select the Image Texture Node you want to Bake the Texture to:

Did you watch: https://cgcookie.com/courses/bake-texture-baking-with-blender already?

That course is a must watch if you're going to do anything with baking. Chunck goes through all the gotcha's. 

Was it also the Active one?

And you also need to have an Unwrapped Object Selected, so you have UV's to Bake on.

Does Blender give you an Error message when you try to Bake? 

And if so, what does it say?

Maybe you don't have any Light in your Scene.

You could also Bake it like this:

That would  give an Albedo Map.

The most neutral Diffuse would be with a World set to white and no other Lights. You'd still get the Indirect Diffuse, because you havee that enabled.

Here you can clearly see how the Lighting affects the Diffuse Baking:

So if you have no Lights (and a black/dark grey world), your Bake will be black (dark grey).

Perhaps this is one of those that is better to have the blend file to investigate. You can upload it to google drive or dropbox and paste the link. And don't forget to collect all the resources and pack it into the blend file. 

Hi Muqqadas,

That Link gives an Access Denied.

Same here. You have to make it public.
